Quiksilver managers told analysts at the ICR Xchange investor conference a few days ago that they see opportunities for growth in spite of strong competition in the action sports market from the likes of Billabong, Nike, VF Corp., PPR and Abercrombie & Fitch. In the next five years, untapped geographical markets such as China and South Korea could add $300 million in sales. Another $200 million could come from e-commerce by pushing it up from 2 to 10 percent of sales. The group could grow by $100 million in the women's segment under the Quiksilver, Roxy and DC brands. The DC brand could double its sales and reach an annual level of $1 billion.
